Abstract

Recent advances in microfluidic technology highlight electrowetting for its programmability and precision. However, traditional electrowetting chips face limitations in scalability due to fixed electrode sizes. Optoelectrowetting (OEW) offers a solution with light-controlled virtual electrodes, but droplet splitting remains challenging. This study introduces a parallel-plate OEW chip, enhancing droplet manipulation and achieving rapid splitting with light-controlled dark stripe electrodes. We proposed the dimensionless parameter η to characterize droplet splitting, and a mathematical model describes key factors influencing controllable splitting, providing valuable design guidelines for OEW chips.
